Abstract: A low profile hermetic electrical connector includes a conductive layer with opposite first and second conductive layer surfaces. An inner electrical isolation layer is coupled between the first conductive layer surface and a first contact and an outer electrical isolation layer is coupled between the second conductive layer surface and a second contact. A contact interconnector electrically couples the first contact and the second contact through the inner electrical isolation layer, the conductive layer, and the outer electrical isolation layer without electrically contacting the conductive layer, creating a serpentine, low flow path for vapor through the adhesive layers. In a hermetic electrical cable end connector, the first contact is electrically coupled to a first conductor through a first interconnector and a second contact is electrically coupled to a second conductor through a second interconnector. Two additional electrical isolation layers are required.

Abstract: A double integrating silicon acceleration sensing device which is solid state and micromachined measures the acceleration of an object and determines the distance travelled by that object through its trajectory. The device comprises a hermetically sealed container. The cavity within the container is divided by a flexible silicon diaphragm into two separate cavities, one shallow and the other deep. The two cavities are filled with a fluid which is relatively incompressible over the range of operating pressure. The fluid can only transfer between the two cavities through an orifice. Two capacitor plates form a capacitor within the shallow cavity. One of the plates is secured to a central portion of the diaphragm, and the other plate is secured adjacent to and opposite of the first plate within the shallow cavity. When the accelerometer is at rest, the two plates are separated by a given distance X.sub.g.

Abstract: A projectile having a piercing front end with a solid lubricant molded on the front surface for reducing friction during penetration. The lubricant is molded in a shape to receive an antenna and other electronics. The front end also has an axial hole formed therein to enhance self destruction from the sudden release of compressional strain energy accumulated during penetration through a hard target.

Abstract: A turns-to-arm sensor which uses a piezoelectric crystal to produce a current flow dependent upon the spin rate of a projectile. An output voltage is produced across a diode, from said current, which is proportional to the square root of the voltage at the crystal. The output voltage is approximately equal to the angular velocity of the projectile and is converted to frequency. The frequency determines the rate at which a preset counter operates. At time-out of the counter an arming signal is sent.

Abstract: A microminiature oscillator that uses the movement of a mechanical structure placed on an etched silicon chip to control the frequency of a pulse used as a time base in electronic applications.

Abstract: The present invention consists of a safe and arming device and method that utilizes a combination of linear and angular accelerometers to determine the type of weapon being used. From a determination of the type of weapon an arming distance is looked-up and divided by the linear velocity to provide an arming delay time. When the delay time has elapsed an actuator is activated thereby arming the munition.

Abstract: The present invention consists of an apparatus for damping the movement of a microbeam sensor. The damping device consists of a gold plated chrome bar, or the like being placed, or fabricated, above the microbeam. This damper prevents excessive movement that could be caused from harmonic vibrations or the like.

Abstract: A centrifugal rotor operates under the influence of the spin of the fuze to close a switch for a fraction of a fuze revolution. The switch closure controls a counter which counts the cycles of a relatively high frequency oscillator for the fraction of a revolution. This fractional count is multiplied by a constant to attain a required total number of revolutions. A second counter counts the cycles of the oscillator from the time the oscillator is turned on until the total revolution count is attained, at which time the fuze is armed.

Abstract: An improved safe and arming device for isolating the fuse from the main eosive charge in spin stabilized shells to prevent premature detonation of such shells. The improved safe and arming device comprises a housing adapted to be positioned intermediate of the fuse and the main explosive charge of such shells for rotation therewith about a shell spin axis when the shell is fired, a rotor mounted in the housing for rotation about a rotor axis, and a rotatable control member engageable with the rotor and being rotatable about an axis extending in the same direction as the rotor axis for controlling the rate of rotation of the rotor. The rotor is positionable in a desired start position and is adapted to rotate in response to rotation of the shell to an armed position to communicate a detonation signal from the fuse to the explosive charge.
